Just to add onto Chris' email. This sounds like a good place to suggest people purchase Jeremy Keith's book HTML5 for Web Designers. In it he actually describes the semantics of the new tags and gives defines when and how to use tags like <section> <article> <header> <footer> etc. If you have questions like these definitely pick this book up as it will help clear up the confusion. Also as far as <section> goes there is not much difference between it and <div> as <section> is suppose to be used for grouping of thematically similar content. The difference between the two is that <div> has no semantic meaning and doesn't tell you anything about the content whereas section does. -- ------------------------------------------------------------------------------------ Jason Arnold http://www.jasonarnold.net ------------------------------------------------------------------------------------ ******************************************************************* List Guidelines: http://webstandardsgroup.org/mail/guidelines.cfm Unsubscribe: http://webstandardsgroup.org/join/unsubscribe.cfm Help: memberh...@webstandardsgroup.org *******************************************************************
